Use the String() method in JavaScript to convert to String. You can try to run the following to learn how to convert [ ] to String in JavaScript.ExampleLive Demo           Convert [] to String                var myVal = [];          document.write("String: " + String(myVal));          

The shiftkey mouse event property is used to show whether SHIFT key is pressed or not when mouse button is clicked.ExampleYou can try to run the following code to learn how to implement shiftKey Mouse event in JavaScript.           Press and hold SHIFT key and then click here.                function funcShiftKey(event) {             if (event.shiftKey) {                alert("SHIFT key: Pressed");             } else {                alert("SHIFT key: NOT Pressed");             }          }          

When an event is triggerd, the screenX mouse event returns the horizontal coordinate of the mouse pointer.ExampleYou can try to run the following code to learn how to implement screenX Mouse event in JavaScript.           Click here to get the x (horizontal) and y (vertical) coordinates of the mouse pointer.                function coordsFunc(event) {             var x_coord = event.screenX;             var y_coord = event.screenY;             var xycoords = "X coords= " + x_coord + ", Y coords= " + y_coord;             document.write(xycoords);          }          

Use the Number() method in JavaScript to convert to Number. You can try to run the following code to learn how to convert [50, 100] to Number in JavaScript − Example Live Demo Convert [50,100] to Number var myVal = [50,100]; document.write("Number: " + Number(myVal));

When a mouse event is triggered, the pageX mouse event property is used to get the horizontal coordinate of the mouse pointer. The coordinate is relative to the screen.ExampleYou can try to run the following code to learn how to implement pageX Mouse event in JavaScript.                    Click here to get the x (horizontal) and y (vertical)          coordinates of the mouse pointer.                        function coordsFunc(event) {             var x_coord = event.pageX;             var y_coord = event.pageY;             var xycoords = "X coords= " + x_coord + ", Y coords= " + y_coord;             document.write(xycoords);          }          

The ctrlkey mouse event property is used to show whether the CTRL key is pressed or not when the mouse button is clicked.ExampleYou can try to run the following code to learn how to implement ctrlKey Mouse event in JavaScript.           Press and hold CTRL key and then click here.                function funcCtrlKey(event) {             if (event.ctrlKey) {                alert("CTRL key: Pressed");             } else {                alert("CTRL key: NOT Pressed");             }          }          

Use the Number() method in JavaScript to convert to Number. You can try to run the following code to learn how to convert -Infinity Number in JavaScript.ExampleLive Demo           Convert -Infinity to Number                var myVal = -Infinity;          document.write("Number : " + Number(myVal));           OutputConvert -Infinity to Number Number : -Infinity

When a mouse event is triggered, the clientX mouse event property is used to get the horizontal coordinate of the mouse pointer. This is according to current window.ExampleYou can try to run the following code to learn how to implement clientX Mouse event in JavaScript.                    Click here to get the x (horizontal) and y (vertical) coordinates          (according to current window) of the mouse pointer.                      function coordsFunc(event) {             var x_coord = event.clientX;             var y_coord = event.clientY;             var xycoords = "X coords= " + x_coord + ", Y coords= " + y_coord;             document.write(xycoords);          }
